Figure 11-9. The general reflex arc.
(a) An automatic reaction to a stimulus (without first having conscious
sensation) is referred to as a reflex. (As an example: The withdrawal of the hand from

(b) The pathway from the receptor organ to the reacting muscle is

(a) The stimulus is received by a receptor organ.
(b) That information is transmitted to the CNS by the afferent (sensory)
